​After a weekend spent tweeting about the NFL and NBA, President Trump saved his biggest announcement for Sunday evening. President Trump signed a new proclamation with new restrictions on entry to the U.S. for eight different countries.

The new rules, which will impact the citizens of Chad, Iran, Libya, North Korea, Somalia, Syria, Venezuela and Yemen, will go into effect on October 18.

The restrictions rage from full travel bans on nationals from countries like Syria to more targeted restrictions. A suspension of non-immigrant visas to citizens for Venezuela, for instance, applies only to senior government officials and their immediate families.

The announcement comes the same day as Trump's temporary ban on visitors from six Muslim-majority countries is set to expire, 90 days after it went into effect. That ban had barred citizens of Iran, Libya, Somalia, Sudan, Syria and Yemen who lack a "credible claim of a bona fide relationship with a person or entity in the United States" from entering the U.S.

"As President, I must act to protect the security and interests of the United States and its people," reads the proclamation.

Officials stressed that valid visas would not be revoked as a result of the proclamation. The order also permits, but does not guarantee, case-by-case waivers .
